With how Sega & Atlus have been so cozy with Game Pass of late, I'm almost half-expecting Persona 6 to be a Day 1 Game Pass title. And I would in no way blame the fanbase on PlayStation if they decided to feel some kind of way about that, even if they decided to not buy it on PlayStation and just get a cheap Game Pass offer for a couple of months and play the game that way (because I'm almost certain the Atlus + Game Pass deals are counting on players still buying the games on
Sony & Nintendo platforms to hit revenue targets).
Kadokawa as an acquisition for Sony might be a challenge precisely because of the anime stuff. Sony have already amassed a LOT in terms of anime streaming platforms and content the past few years; getting Kadokawa on top of that even if just for From Software might present some complications. Sony would probably need to talk Kadokawa into selling off From Software, but then that might cause issue with Bandai-Namco since they've been publishing From Software's games globally for a while, and it's not like Sony would need another company to publish From Software games post-acquisition. I also think that's a potential situation Sony just doesn't want with a valued 3P partner, all things considered.
So the best thing they could probably aim for is buying more shares into From Software and investing into From Software software development. Buying shares & making investments into Kadokawa themselves would also be smart. If Sony were to say invest into growing From Software's team size, that could enable a means of possibly getting a co-developed exclusive out of them without impacting From Software's regular multiplatform development plans, meanwhile that same investment can serve From Software on their other games when they aren't working on an exclusive for Sony, as just one example.
